Our bodies are funny things when ttc!! With PCOS ur periods can be very irregular, heavy and mire painful that most. I know when I came off the pill I have an average of 33 day cycle then after almost a year they started getting further apart and then just not getting them at all!!

Sometimes ur body randomly misses out a period.

It could also b that u ovulated later than normal and it's a bit early to test.

Unfortunately I don't know for sure. If ur worried or want to talk it through I'd suggest u speak to ur doc

I had regular periods (ever 5 weeks, on the dot) for a couple of years, but then they started gradually lengthening, then were cocked up altogether after I had a m/c. I found this coincided with weight gain, so I think that exacerbated my pcos.
